codsh 0.23.0 — Mission Contract: `/ship` that won't silently drift

A developer released codsh 0.23.0, a DeepSeek-native terminal coding agent built on the open dsh harness, introducing a Mission Contract control plane for its /ship command. The contract compiles sealed acceptance criteria into a machine-checkable mission.contract.json so that scope drift blocks a run instead of silently rewriting the goal, and delivery requires recorded evidence. The release also adds a wayfinder step before the grill interview and tighter parent/subagent coordination, distributed via the codsh-cli and codsh-bundle npm packages.

codsh is a DeepSeek-native terminal coding agent on open dsh. It is not a Claude Code env wrapper.

The hook stays the same: /ship takes one sentence to verified code.

0.23.0 ships the Mission Contract control plane for that loop — so acceptance criteria stay sealed, drift blocks the run instead of rewriting the goal, and delivery needs recorded evidence.

When Gate 1 confirms the spec, /ship compiles a machine-checkable Mission Contract (mission.contract.json) from the sealed Main Track, Out of Scope, and acceptance criteria.

After seal:

Also in this release: wayfinder before the grill interview (destination + open decisions, separate from implementation), and tighter parent/subagent coordination — one parent-owned ticket per turn, fresh-context children for investigation / landing / review, parent keeps questions, gates, and final proofs.

npm: codsh-cli + codsh-bundle 0.23.0.

Ad-hoc agent plans live in conversation memory. They drift. Acceptance becomes vibes.

/ship keeps the human projection in Markdown and the runner-owned contract on disk:

While work is in flight you get a panorama: TTY overlay (Ctrl+G), a ticket-count teaser with the local Web flowchart URL, and the flowchart itself — /ship does not auto-open a browser.

Coming from Claude Code / Codex? Different harness, different product. Redirecting Claude Code at DeepSeek with env vars works; this is the native path on dsh. Map what maps / what’s missing on issue #64.

Then:

/ship let long diffs open in a pager instead of scrolling past

For tiny edits, plain chat or ⇧Tab plan mode is enough — /ship is multi-phase and burns tokens on purpose.

codsh-cli`` codsh-bundle Early project. Sharp edges welcome — especially Windows (#62) and third-party endpoints (#63).
